Description

一种自然通风高防护等级模块化预装式变电站 技术领域
本实用新型涉及一种变电站，特别涉及一种箱式变电站。
背景技术
随着社会的发展，特别是城市经济的快速发展和人口的逐渐增加，人们对土地的需求越来越大，建筑用地日趋紧张。作为不可再生的资源，国家对土地的管控越来越严。所以，占地面积多的变电所新建越来越少，而占地面积小且功能齐全、运输安装方便的预装式变电站得到广泛应用。
普通标准的预装式变电站是将高压开关柜、配电变压器、低压开关柜等配电、控制设备组合安装在一个长方形外壳的箱体中。外壳内部隔有相互独立的高压室、变压器室、低压室，三室成“目”字形或“品”字形排布。但是，因为变压器安装在变压器室中，变压器室在满足足够的防护等级(标准要求≥IP33)要求时，变压器室散热就受到限制，即使有时在变压器室加装轴流风机，散热效果也不会很好且会增加风机嗓音影响周围环境。散热效果不好，变压器容量得不到充分的利用，变压器的利用率就会降低，这就造成资源的白白浪费。

与现有技术相比，本实用新型的有益效果在于，将变压器室设置成开放式结构，使得变压器能够四周自然通风，并且将变压器室、高压室和低压室相互隔离，独自成室，提升了变电站的防护等级，能够解决箱式变电站的外壳防护等级低且变压器室散热效果不佳的问题，使得变压器的容量得到充分的利用，提升了变压器的利用率，扩大了箱式变电站的应用范围，本实用新型可用于箱式变电站。
作为本实用新型的进一步改进，所述高压室设置在箱体的第一侧面，所述低压室设置在箱体的第二侧面并且与高压室首尾相连，所述变压器室设置在高压室和低压室围成的“L”形内侧里，这样使得变压器室和高压室以及低压室之间的间隙更大，有更充足的空间进行散热。
作为本实用新型的进一步改进，所述变压器室的外周设置有网门结构，并且变压器室的顶部设置有架空顶盖，使变压器的四周都能自然通风，变压器室的外周设置有网门结构，进一步提升了安全性，并且变压器室的顶部设置有架空顶盖，这样可以遮挡太阳光对变压器的直接照射，降低了变压器的环境温度，很好的解决了变压器在使用过程中，因散热不足而造成变压器降容的现象。
作为本实用新型的进一步改进，所述高压开关设备与变压器之间采用全绝缘可触摸式的电缆插接头连接，所述电缆插接头外周设置有保护罩，这样可以提升变电站的安全性能，使得变电站的防护等级得以更进一步地得到提高，同时方便现场安装使用时的快速插接。

作为本实用新型的进一步改进，所述低压开关设备包括低压总柜，所述低压总柜与低压出线柜相连，所述低压出线柜与无功补偿柜相连，所述无功补偿柜与远程控制箱相连，所述无功补偿柜内设置有一体式智能无功补充电容器，采用共分补混补形式，所述低压总柜和低压出线柜中所装配的断路器采用手动或电动操作，可通过配电终端实现远程操作。
